was there ammonia before?? 
If not then I would do a huge water change and pull the carbon and the snow until you know which it is.  
I can't remember didn't Marineland have a bad batch of carbon before?....  
I know I stopped using the stuff myself. 
 
do you always have microbubbles stuck to the rock like that?
